Introduction
The title of this work will no doubt raise several questions in many readers’
minds: why the Caribbean? why not the Caribbean and the Gulf of Mexico?
why only the marine isopods? just what is the “Caribbean area”? We hope
that the answers to some of these (and other) questions will become
apparent.
There are several works that already deal with the isopods of the Carib-
bean, as part of a wider treatment of North American isopods (e.g.,
Richardson, 1905; Schultz, 1969). Why then this “Isopods of the Carib-
bean”? As partial answer, the following: many new records of isopods from
the Caribbean region (in its broadest sense) have appeared in scattered pub-
lications in the last few decades. The time has come to pull these together in a
single work. The number of marine laboratories in the area has increased,
with more and more students exploring especially the shallow marine en-
vironment. A single work on a relatively speciose and abundant group of
invertebrates would be useful to such investigators, as they build up a com-
prehensive view of the biology of the region. Concepts of the taxonomy of
several isopod groups have changed radically over the last few years; again,
there is obvious utility in having these changes summarized in a single
source. New species and records are continuously being found. Having a
single baseline work decreases the time needed for investigating and estab-
lishing the validity of such records.
HISTORIC BACKGROUND
The history of isopod taxonomic research in the Caribbean really starts with
a worldwide monographic work on the Cirolanidae by Hansen in 1890. In-
cluded here were about 12 species from the Danish West Indies, now the
U.S. Virgin Islands. Since then a few major works on Caribbean isopods
have appeared, such as Moore’s report on the isopods of Puerto Rico (1901)
and Menzies and Glynn’s report on the same area (1968). Some areas have
received considerable attention, such as the aforementioned Puerto Rico and,
more recently, Belize. A list of 116 species of isopods from Cuba (including
Oniscidea) has been published (Ortiz, Lalana, and Gomez, 1987). At the
other extreme, there are no records from a number of localities, especially the

islands of the southeastern chain of the Lesser Antilles. In total there are
about 40 publications, varying from descriptions of single species to longer
works, that deal with isopods from the Caribbean. These publications will be
encountered in the following guide, under the specific taxa.
GEOGRAPHIC AREA COVERED IN THIS GUIDE
The accompanying map (Figure 1) shows the area for which records are
included in this guide.
While it may seem logical to include the Gulf of Mexico, and while there
are several isopod species common to both areas, this has not been done.
There are relatively few isopod records from the Gulf; undoubtedly a great
deal of taxonomic work awaits the careful collector in this area. Also, from a
zoogeographic point of view, separation of the Gulf may be justified.
Bermuda, on the other hand, situated in the northwestern Atlantic several
hundred miles off the coast of the United States, is included. This island,
although remote from the Caribbean, is swept by waters that earlier have
passed through the Caribbean. Zoogeographically, the shallow-water Ber-
mudan and Caribbean faunas have much in common.
While perhaps not strictly in the Caribbean Sea, the Bahamas and the
Florida Keys are included here, their shallow-water marine faunas being
overwhelmingly Caribbean in nature.
Turning to depths limits, within the area under discussion, species from
the intertidal to 200 meters have been dealt with in some detail. This arbi-
trary cutoff depth was selected because most Caribbean isopod species in-
habit relatively shallow depths. About 30 species have been recorded from
below 200 meters in the Caribbean, many of these known only from the type
material. A list of species of this very poorly known deeper fauna is included
here. Without doubt, many species in the deeper waters of the Caribbean
await discovery.
A fascinating group of isopods, while not strictly shallow-water marine
forms, is included. These are the true cave forms, found mainly in the sub-
orders Anthuridea and Flabellifera. Given the history of the Caribbean from
the Quaternary to the present, it is not surprising that caves are common
throughout the region. These caves may be well inland and contain only
freshwater, but are more commonly anchialine, that is, having some (fre-
quently subterranean) link to the sea. Less common, and of lesser interest
from an isopod taxonomist’s point of view, are the fully marine caves in
direct communication with the sea or, indeed, under the surface of the sea
itself.
4 INTRODUCTION
ARRANGEMENT OF THE GUIDE AND HOW TO USE IT
A short introduction to the Crustacea Isopoda is provided, followed by a
glossary of descriptive terms and morphological features used throughout the
guide (see Figure 2).
Keys and diagnoses to the suborders and all lower taxa follow. For ease of
usage, except in the keys, all taxa are presented in alphabetical order, regard-
less of their phylogenetic relationships.
Diagnoses are provided for all suborders, families, genera, and species.
The only exceptions to this are in the suborders Epicaridea and Oniscidea.
Within each suborder, a key to the families occurring in the Caribbean is
provided. Similarly, within each family and genus, keys are provided to the
relevant genera and species, respectively.
In whatever context, where an author and date appear, a reference to these
is provided in the Literature Cited section. In some cases, reference is made
to useful publications such as revisions of families or genera.
As this is not a textbook on the Isopoda, biological information is generally
kept to a minimum. In the case of individual species, however, what little
ecological information is available, is provided. For general texts on biology,
internal anatomy, physiology, and reproduction, the reader is referred to
works such as Kaestner (1967), Waterman (1960), Bliss (1982-1985), and
Schram (1986).
Within each species discussion, a diagnosis is given, along with maximum
(total) middorsal lengths for males and females, where known. The diag-
noses are not exhaustive, but provide only the information needed to distin-
guish the species. Diagnoses thus vary in length from the statement of a
single feature to a paragraph concerning several features, depending on the
understanding and complexity of the taxonomy of the group. In the longer
diagnoses, morphological features are dealt with in order from anterior to
posterior on the animal’s body. Records are given, rather than geographical
distribution, as our knowledge of many species is woefully incomplete. These
records are given in a roughly north-to-south order; records outside of the
Caribbean region, as here defined, are given on a separate line. A few species
not yet recorded from the Caribbean are included, in the strong likelihood
that they will eventually be found here. The records include depth distribu-
tion information in meters, where known. Records were taken from pub-
lished papers; in addition, the collections of the United States National
Museum of Natural History, Smithsonian Institution, were scoured, and
many unpublished records from this source are also included. In the “Re-
marks” section, ecological information such as substrate preferences is given.
Hosts of parasitic species are given. Formal synonymies are not provided,
INTRODUCTION 5
but nomenclatural comments are included in the few cases where a species
may be known under a more commonly used name. Usually, a figure of the
entire animal of each species is given. Diagnostic features are usually illus-
trated. Unless otherwise stated, all illustrations are original and by the au-
thors, and were made from actual specimens.
Common and scientific names of fishes that are hosts to parasitic isopods
are taken from the American Fisheries Society special publication no. 12
(Robins et al., 1980).
Finally, a word of warning. Difficulties may be experienced in using the
keys, for which there may be any of several reasons: characters seen in the
animal may not clearly conform to those in the key (in which case refer to the
figures, as well as to good recent descriptions or diagnoses); your material
may be a new record for the region; or you may have an undescribed species
(in which case refer to more comprehensive treatments of the group).

Suborder Anthuridea Leach, 1814
DIAGNOSIS Body generally elongate and subcylindrical. Eyes absent in
some genera. Antennular peduncle of three articles; antennal peduncle of five
articles. Mandible with palp of one to three articles, or absent; body of mand-
ible either styliform and lacking molar and lacinia mobilis, or with molar
variously specialized or reduced, lacinia mobilis absent, and spine-row modi-
fied to form platelike lamina dentata. Maxilla 1 with inner ramus reduced,
outer ramus slender. Maxilla 2 rudimentary. Maxilliped variable, with palp
of one to five articles, endite present, modified, reduced, or absent. Pereonite
1 free. Pereopod 1, or pereopods 1—3 subchelate; pereopods 4—7 generally
ambulatory. Pleonites 1—5 free or fused, pleonite 6 partly or completely fused
with telson. Pleopods 1—5 similar, or pleopod 1 variously modified to form
operculum. Uropodal exopod often folded dorsally over pleotelson.
Pleotelson with pair of statocysts, with single statocyst, or lacking statocysts.
REMARKS Protogyny has been demonstrated in several species of An-
thuridea. The order of development in these cases is: egg, manca (both in the
broodpouch), immature subadult, ovigerous female, premale, male, with
varying numbers of molts between each stage. At least one molt takes place
between ovigerous female and premale, the latter being distinguished by the
loss of the oostegites and by the elongation of, and acquisition of more flagel-
lar articles in, the antennule. One or two molts take place between premale
and sexually mature male, the latter being characterized by the possession of
elongate antennular flagella bearing dense whorls of aesthetascs, a more set-
ose and/or spinose pereopod 1, and sometimes by an elongation of the pleon
and uropods. In some genera, the males have somewhat atrophied
mouthparts, suggesting that they do not feed at this stage. As a result of this
seemingly widespread protogyny, sex ratios are strongly biased toward
females, and in several species males are not yet known.
The number of families in the suborder Anthuridea has not been settled.
At present, three families are recognized. Doubtless, further families will be
defined and the genera reshuffled.

REMARKS _ The ten species of Stygocyathura from the area covered in this work
are morphologically very similar, with specific differences, although real,
being very subtle. A dichotomous key would be cumbersome and require
considerable dissection of mouthparts. The copulatory stylet of the male pro-
vides a valuable specific feature but males are not always available. Instead
of a key, we have provided a list of species with their total lengths and lo-
calities (Table 1). Given the very restricted distribution of these cave species,
material from localities not listed here should be treated as potentially un-
described, and the material compared with descriptions, especially those of
Botosaneanu and Stock (1982).

REMARKS Malacanthura cumanensis Paul and Menzies, 1971, described from
the same locality as M. caribbica, was shown to be the latter species (Kensley,
1980).
Mesanthura Barnard, 1914
DIAGNOSIS @: Dorsal integument with (usually) species-specific pigment
pattern; pigment persistent in alcohol. Mandibular palp of three articles,
terminal article with row of spines, number of which specific for species.
Maxilliped with endite either very reduced or absent; palp of three articles,
with terminal article usually about half length of penultimate article, suture
transverse. Pereopod 1, propodus expanded, palm often with step. Pereopods
2 and 3, propodi not expanded. Pereopods 4—7, carpi roughly triangular,
with anterior margin shorter than posterior margin. Pleonites 1—5 fused,
pleonite 6 dorsally demarked. Pleopod 1, exopod operculiform. Telson with
two basal statocysts. d: Eyes larger than in 2. Antennular flagellum of sel-
dom more than 10 articles bearing numerous aesthetascs. Mouthparts, espe-
cially body of mandible, reduced. Pereopod 1, propodus bearing dense band
of spines on mesial surface near palm. Pigment pattern more diffuse than in
2, extending onto ventral surface.
REMARKS Méesanthura is a relatively large genus of about 30 species, re-
corded from most tropical and temperate seas, in shallow habitats. The
males of few species have been recorded; by themselves, males are difficult to
identify as the dorsal pigment pattern characteristic of the female breaks
down and spreads onto the ventrum.

REMARKS The inability to place Mexicope in a family reflects the fact that
the arrangement of the families and genera of the Janiroidea is still unsettled.
While having affinities with the Pleurocopidae and the Janiridae, placement
in either of these would require redefinition of both families, making the
Janiridae even more of a hodgepodge of phylogenetically unrelated genera.

REMARKS This genus has been, and continues to be, a source of taxonomic
problems. Several authors (e.g., Pires, 1980) have separated the species into
the genera Carpias and Bagatus; others (e.g., Bowman and Morris, 1979) have
synonymized them. In part, this uncertainty reflects the general uncertainty
of the state of taxonomy in the family Janiridae. In this work, the genus
Carpias is used to contain all the species described under the names Carpias
and Bagatus.
While these tiny asellotes are frequently extremely abundant in certain
habitats (e.g., in reef-crest algal turfs; Kensley, 1983), difficulty is experi-
enced in identifying specimens other than mature males. The first pereopod
of the mature male is the feature best used for species separation, but varia-
tion with maturity and geographic locality have not been investigated. With
more detailed work, some species will undoubtedly be synonymized.

EPICARIDEA 107
Suborder Epicaridea Latreille, 1831
DIAGNOSIS’ Predominantly ectoparasites of marine crustaceans, feeding on
blood. Eyes sessile, usually present in d, often reduced or lost in 2. Anten-
nae and antennules reduced; mouthparts reduced, forming a suctorial cone
containing pair of piercing stylets formed from modified mandibles. Maxillae
1 and 2 reduced or lost. All mouthparts may be lost, and replaced by pro-
boscis. d small and isopodlike. 2 undergo considerable distortion or reduc-
tion, often to unsegmented sacs of eggs in some forms. Ostegites usually re-
tained. Two larval mancalike stages, epicaridium and cryptoniscium (Figure
49), characteristic of entire suborder.
REMARKS The epicarideans are ectoparasites of other crustaceans, with the
juveniles often using copepods as intermediate hosts. Sexual dimorphism is
marked, the males being symmetrical with unambiguous segmentation, and
considerably smaller than the often highly distorted females. In these, body
segmentation is often obscured, with body segments often expanded on one
side and reduced and compressed on the other. The marsupium of the
ovigerous female, except in the Cryftoniscidae and Entoniscidae, is made up
of broadly lamellar oostegites, is relatively enormous and often obscures the
rest of the body structure.
Crustacean hosts of the epicarideans are found in four classes: Ostracoda,
Copepoda, Cirripedia, and Malacostraca, and in nine orders of the Mal-
acostraca: Leptostraca, Stomatopoda, Mysidacea, Cumacea, Tanaidacea,
Isopoda, Amphipoda, Euphausiacea, and Decapoda. The Epicaridea have
been divided into two superfamilies, the Bopyroidea, containing families
Bopyridae, Dajidae, and Entoniscidae, and the Cryptoniscoidea, containing
the Crytoniscidae.
In the Bopyridae (Figure 50), the often asymmetrical adult female shows
some segmentation. Seven pereopods may be present only on one side, their
number being variable on the other. This is largest of the epicaridean fam-
ilies, containing over 400 species (Markham, 1974). Ten subfamilies have
been recognized: the monotypic Entophilinae parasitizes galatheid crabs; six
subfamilies, the Argeiinae, Bopyrinae, Bopyrophryxinae, Ioninae, Pseu-
dioninae, and Orbioninae are all branchial parasites of decapod crustaceans;
two subfamilies are abdominal parasites, the Phyllodurinae on callianassid
mud-shrimps, and the Athelginae on hermit crabs; the Hemiarthrinae are
known from the dorsal and ventral abdominal surfaces, and from the
branchial chamber of caridean shrimps.
The Dajidae are ectoparasites pelagic mysidaceans, euphausiaceans, and
decapod caridean shrimps. Adult females are often found unattached in
plankton and pelagic samples. When attached, dajids are found on the

cephalothorax of the host, attached dorsally to the carapace, ventrally and
laterally in the gill chambers and on the pereopods, or in the brood
chambers.
The Entoniscidae are internal parasites of decapod crustaceans, being
found in the visceral cavity, with the parasite’s head in the position of the
host’s gonads or hepatopancreas. Veillet (1945) demonstrated that a pore to
the host’s branchial chamber connecting the parasite to the exterior is pres-
ent only in hosts with mature parasites, to facilitate the release of epi-
caridium larvae.
The Cryptoniscidae are protandrous hermaphrodites. The female is

reduced to a simple or lobed sac, generally without appendages. The brood-
pouch is formed by invagination of the ventral body wall. The eggs are re-
leased by the bursting of the sac. Cryptoniscids have been recorded as
parasites of ostracods, cirripedes, mysidaceans, amphipods, isopods, and
cumaceans. The majority feed on blood, but the females of some forms have
been reported to be egg predators.
Given the highly variable morphology of the epicarideans, and the neces-
sity of examining large series of specimens, keys are not provided and species
are not treated individually here. As there is a degree of genus- and species-
specificity for the hosts, Table 2 is provided to give a clue to the possible
identity of a specimen. The student is then advised to consult one of the
detailed works on the group. The most useful single work on the speciose
Bopyridae for the area covered here is Markham (1985).

will undoubtedly show the Flabellifera to be an artificial polyphyletic group.

116 FLABELLIFERA * AEGIDAE
Pleopods biramous, bearing plumose marginal setae. Uropods forming tail-
fan with pleotelson. Pleon of four or five free pleonites plus pleotelson.
REMARKS Although these large isopods (up to 60 mm) are often referred to
as fish parasites, Brusca (1983) prefers the term “carnivorous scavengers and
micropredators,” as they attach to fish hosts infrequently and only long
enough to feed. When feeding, they engorge themselves on the host’s blood.
Aegids show almost no host- (or rather prey-) specificity, being opportunistic
feeders, and are most frequently captured by bottom trawls on the ocean bed.
In ovigerous females, the maxillipedal articles become expanded and, along
with the anterior oostegites, cover the buccal field, thereby making feeding
impossible.

are E. mexicana Richardson, 1905, from the Gulf of Mexico, and E. delaneyi
Excorallana 161
Stone and Heard, 1989, from the northeastern Gulf of Mexico. The latter
species, particularly, could conceivably be encountered in the Florida Keys.
Delaney (1984) provides a useful review of the genus Excorallana, and of the
distribution of the species.

Family Cymothoidae Leach, 1818
DIAGNOSIS. Antennules and antennae reduced, no clear distinction between
peduncles and flagella. Mandibular palp of three articles. Maxilla 1 with four
terminal spines. Maxilla 2 apically bilobed, armed with several spines. Max-
illipedal palp of two articles, terminal article bearing hooks. All seven pairs of
pereopods prehensile, ending in strongly hooked dactyli. Pleopods lacking
marginal setae in adults.
REMARKS The cymothoids are exclusively ectoparasites on marine, fresh-
water, and brackish-water fishes. Most cymothoids occur in shallow water,
mainly in tropical and subtropical areas. The position of attachment on the
host (externally, in the buccal cavity, or in the gill chamber) is usually genus-
or species-specific. The body of gill parasites is often asymmetrical, being
slightly twisted, perhaps an effect of the position on the host. The mouthparts
are highly adapted for the parasitic mode of life, while all seven pairs of
pereopods are strongly prehensile. The posterior pereopods of some genera
have the basal article expanded and carinate, allowing for increased mus-
culature. The secretion of anticoagulants in the juvenile stages further aids
the blood-feeding habit. The surface area of the pleopods is often increased
by the development of lobes on the bases or the lamellae, providing an in-
creased respiratory ability.
The post-mancal juvenile stages (sometimes referred to as the aegathoid
stage) have large eyes, and highly setose pleopods for active swimming. The
juveniles will attach themselves indiscriminantly to any convenient fish host,
but eventually attach to the preferred host-species. The juvenile then de-
velops into a functional male, losing the swimming setae of the pleopods.
Both juveniles and males feed actively, drawing blood from the host fish. The

male eventually becomes a female (all cymothoids are protandrous) should a
female not already be present. In some species, the female is nonfeeding. In
those species which settle either in the mouth cavity or gill chamber of the
host, integumental pigment is frequently lost, and the eyes become reduced.
Given the highly variable morphology of the cymothoids, in part imposed
by the parasitic mode of life, and the existence of polymorphism and possible
sibling species, the taxonomy of this family demands the examination of large
numbers of specimens. As a further aid to identification, Table 3 is provided,
giving host species, parasite, and site of attachment.

194 FLABELLIFERA ¢ LIMNORIIDAE
REMARKS This family includes a number of species that are of considerable
economic importance. Given that species of Limnoria are wood borers,
wooden structures such as wharf pilings that are immersed in sea water and
even in water of reduced salinity are vulnerable to attack by these gribbles.
Prolonged exposure can lead to weakening and eventual collapse of these
structures (see Ray, 1959). Even creosote-treated wood is not fully protected;
Limnoria tuberculata will bore into such wood to where the creosote has not
penetrated.
The isopods rasp at the wood fibres with the rasp and file structures of the
mandibles, usually following the grain of the wood. With this boring activity,
saprophytic fungi and bacteria invade the wood and assist in the breakdown
process. Limnoria lack cellulase-secreting microflora in their gut, but proba-
bly secrete a cellulase themselves (Boyle and Mitchell, 1978). It is also prob-
able that the fungi and bacteria, the latter often densely aggregated on the
setae of the isopod, form part of the animals’ diet. In the natural environ-
ment, Limnoria perform an important role in the breakdown of dead wood,
especially in mangrove areas.
Sexual dimorphism of the pleotelson does occur in some species. This as-
pect of the morphology, however, has hardly been investigated.

REMARKS Menzies (1957) discusses three forms of this species: Forma typ-
ica, which lacks a central depressed area dorsally on pleonite 5 and has a pair
of submedian obscurely carinate tubercles on the pleotelson; Forma A, which
has a triangular depressed area dorsally on pleonite 5 and a pair of subme-
FLABELLIFERA * SEROLIDAE 201
dian tubercles supported by strong carinae on the pleotelson; Forma B, hav-
ing a triangular depressed area dorsally on pleonite 5 and an obscurely cari-
nate pair of tubercles on the pleotelson. Given that at least two of these forms
have been recorded occurring together, it would seem that this is merely a
highly variable species.

REMARKS Right into the 1980s this family was routinely divided into three
groups, based on the structure of the two posterior pairs of pleopods:
Platybranchiatae—pleopods 4 and 5 with both rami membranous and lack-
ing branchial pleats; Hemibranchiatae—pleopods 4 and 5 with branchial
pleats on endopods only; Eubranchiatae—pleopods 4 and 5 with branchial
pleats on both rami. These three “groups” were recognized formally as sub-
families by Hurley and Jansen (1977) but the names were not based on con-
204 FLABELLIFERA * SPHAEROMATIDAE
tained genera and were replaced with current subfamily names by Bowman
(1981) and Iverson (1982), the latter providing diagnoses for all five sub-
families. Four of these are represented in the Caribbean area; the fifth, the
Tecticipitinae, contains only the single primarily Pacific genus Tecticeps.
While the subfamilial status now appears to be resolved, many of the gen-
era still require unambiguous diagnoses. The work of Harrison (1984) on the
structure of the female broodpouch, with its various components of
oostegites, internal pouches, and anterior and posterior pockets (Figure 90),
along with the metamorphosis of the female mouthparts (see Figure 96) has
helped enormously to standardize the genera. Nevertheless, these features of
the female remain unknown in several genera. Further, with this stabilization
based on females, many problems of incorrect generic designation have been
uncovered. In this work, Harrison’s generic diagnoses are followed as far as
possible. Where uncertainty exists, this is indicated. In some cases, we may
still be unaware of existing problems: future work will without doubt result in
the shifting of species to different genera, as well as in the creation of new
genera.

REMARKS The genus Dies has twice been recorded from the Caribbean: D.
arndti Ortiz and Lalana, 1980, from Cuba, and D. barnardi Carvacho, 1977,
from Guadeloupe. This genus is distinguished from Cassidinidea solely on the
basis of the penial structure: biramous in Cassidinidea, uniramous in Dies.
Harrison (1984) has pointed out that the separation of these two genera has
not been satisfactorily resolved. The penis of neither the Cuban nor the
Guadeloupan species has been illustrated, but the whole-animal illustrations
of both look suspiciously like Cassidinidea ovalis. Examination of material of D.
barnardi from the Paris Museum supports the view that this species was based
on immature material of C. ovalis. Neither of the so-called species of Dies are
dealt with in this work, both being regarded as junior synonyms of C. ovalis.

DIAGNOSIS 6 3.5mm, ? 2.3 mm. d: Pereonites 4—6 with transverse ridge
over dorsum, ridge interrupted to form short median section. Pleotelson with
two submedian and two lateral rounded tubercles basally, two submedian,
poorly defined ridges in central area; posterior margin tapering in dorsal
view, with slit either just visible or appearing entire. In lateral view, posterior
pleotelson seen to be laterally compressed, forming narrow groove.
RECORDS Puerto Rico, intertidal rocks and algae.
REMARKS Menzies and Glynn (1968) described this species with two vari-
eties, the holotype as D. acutitelson var. typica, and 11 paratypes as D. acu-
titelson var. glabrothorax. The major difference between these varieties lay in
the presence of transverse ridges on pereonites 4—6 in ¢ypica and their absence
in glabrothorax. The holotype, however, at 3.5 mm, would seem to be a mature
male, while all the paratypes are smaller. The differences described by Men-
zies and Glynn (1968) may thus be due to immaturity. As further compara-
tive material is lacking, these varieties (or whatever their true status) are not
recognized here.
Menzies and Glynn (1968, fig. 30a) illustrate D. acutitelson var. glabrothorax
as having scattered tiny granules over the dorsal integument. These were not
seen when the type material was reexamined.
Harrison and Holdich (1982) placed this species in Paradella, based on the
literature. However, the penes for both varieties are shown as short and sepa-
rate, as in Jschyromene. Again, until further mature males and ovigerous
females are seen, the generic placement of this species must remain in doubt.

REMARKS Menzies and Glynn (1968:55, fig. 22f) named and figured P.
caudata var. brevipes from Puerto Rico. This variant was characterized as hav-
ing the margins of the pleotelsonic notch lacking denticles. Given the con-
siderable variation in ornamentation in this species, we feel that no validity
can be given to the name “brevipes.”
This is the commonest sphaeromatid in the Caribbean, and it has very
broad ecological requirements, being found in a wide range of habitats and

REMARKS There is no agreement on whether this species is synonymous
with §. destructor Richardson, 1897. This latter (if distinct) bores into wood
pilings in estuarine waters, while S. terebrans is found in the prop roots of the
red mangrove tree, Rhizophora mangle. In this habitat, the isopods are inter-
preted either as being destructive agents (e.g., Rehm and Humm, 1973) or as
promoting increased root growth (Simberloff et al., 1978). It is unlikely that
the bored wood itself is a source of food for the isopods; rather, as with the
genus Limnoria, the food is probably detritus or fungi and bacteria growing on
the wood fragments in the burrows or on the setae of the appendages.

frequently encountered as a fish parasite, the favored site for sucking the
host’s blood being in the nares. Upton (1987a, 1987b) has shed light on the
unusual life history of at least one gnathiid genus, Paragnathia.
The taxonomy of the Gnathiidae is based almost entirely on males, the
praniza and females of most species being remarkably similar.

Suborder Oniscidea Latreille, 1803
DIAGNOSIS Compound eyes usually present. Antennules usually very short.
Antennae with 4- or 5-articulate peduncle; flagellum varying from few arti-
cles to multiarticulate. Mandibular palp present. Distal articles of maxillipe-
dal palp often reduced. Coxae of pereonites 1—7 usually distinct, expanded.
Pleopods respiratory, often with pseudotrachea; d with pleopod 2, and
sometimes pleopod | as well, modified for copulation. Uropods terminal or
subterminal with terete rami, or ventral and opercular, with reduced rami.
REMARKS The Oniscidea includes all the isopods that have successfully in-
vaded the terrestrial environment. While still in some degree reliant on exter-
nal moisture, their morphological and behavioral adaptations have allowed
them to live in almost all terrestrial habitats, from hot, dry deserts, through
tropical rainforests and grasslands, to cold-temperate niches. Several forms
have successfully inveigled themselves into termite or ant colonies, where
with varying degrees of morphological adaptations they take advantage of
the security of these habitats. A small number of species have evolved to live
in more constantly wet habitats. Several species may be found in the marine
intertidal, either living in and under piles of decomposing litter along the
high-tide line, digging into beach sand, or sheltering in the damp cracks and
crevices of rocky shores. A few may also be found in mangrove swamps.
A breakdown of families, genera, and species is not provided for this sub-
order, but those few species that are commonly encountered in intertidal
habitats are dealt with individually. Schultz (1974, 1984) records several
oniscidean isopods from the Caribbean area.

Zoogeography
FAUNAL PROVINCES
The area under discussion has been divided into several faunal regions or
provinces, of which the Caribbean, West Indian, and Brazilian are the major
ones (Briggs, 1974). The extent and boundaries of the provinces have been
variously defined depending on the group of organisms under discussion.
Inevitably, zones of overlap exist, but for the purposes of this discussion, the
following rough limits have been used.
Brazilian Province: This province stretches from Cape Frio near Rio de
Janeiro in Brazil to the mouth of the Orinoco River in Venezuela. The out-
flow of freshwater from the major rivers of this region has probably contrib-
uted to the isolation of the Brazilian coral reefs and their associated fauna
from those of the Caribbean. This isolation is demonstrated by the consider-
able endemism of the Brazilian reef fauna and that of the Caribbean reef
fauna, with very few species being common to both.
Caribbean Province: This province has two components, a northern part
in peninsular Florida, that stretches from around Cape Kennedy on the east
coast to Tampa or Sanibel Island on the west coast, and a southern compo-
nent that runs from the mouth of the Orinoco River to around Cabo Rojo or
Tampico on the gulf coast of Mexico. The northern Gulf of Mexico is ex-
cluded from this province and is characterized as being warm-temperate,
rather than subtropical (Briggs, 1974:66).
West Indian Province: This includes all the islands of the West Indian
chain, the Bahamas, and the isolated outrider, Bermuda. The West Indian
Province closely approaches the Caribbean Province in the Yucatan Penin-
sula to the north, and between Grenada and Trinidad in the south. There is
also some indication of the isolating effect on the Bahamas of the Florida
Current through the Straits of Florida.
It has been suggested, on the basis of the molluscan fauna, that a relict of
the Neogene Gatunian Province exists around northern Venezuela and Col-
ombia (Petuch, 1982). While several isopod species have been recorded only
from this area, these are all described in a single paper that covers a very
small part of this region (Paul and Menzies, 1971). There is as yet too little
evidence to explore the idea of this relict fauna further.
261
262 ZOOGEOGRAPHY
ANALYSIS OF THE ISOPOD FAUNA
In the following discussion, the West Indian and Caribbean provinces are
treated as one, the isopod faunas offering little evidence to warrant a separate
treatment of each.
It is a truism that for any discussion of the zoogeography of an area to have
meaning, the true extent of the fauna must be known. With the area under
review, collecting effort has been uneven, and the true faunal composition of
many regions is still incompletely known. Obviously, any conclusions based
on such incomplete data are approximate and subject to revision. Neverthe-
less, certain general patterns or trends emerge when the present isopod fauna
is broken down into its components.
The deepwater isopod fauna of the Caribbean (i.e., from deeper than 200
m) has barely been explored, and little is to be gained from discussing the
relatively few species known. A list of these deeper dwelling species is in-
cluded (Table 4).
Although about 280 shallow-water species are covered by this work, cer-
tain categories of species must be excluded, for various reasons, before anal-
ysis can be attempted. Such excluded groups include the species of Oniscidea
(being essentially terrestrial forms and not part of the marine regime); the
cymothoid species and the species of Aegidae (being fish parasites for at least
part of their life history, and whose distribution is complicated by the dis-
tribution and mobility of the hosts); the limnoriids (being wood-borers whose
distribution is more a function of the distribution of floating wood); and the
true cave species (which have a history more reflective of the geological his-
tory of the area than of the marine regime). The epicarideans have a distribu-
tion somewhat complicated by the distribution of their crustacean hosts and
their pelagic epicaridean and cryptoniscan larvae. Nevertheless, the decapod
hosts of the great majority of species covered here are Caribbean endemics,
and inclusion of the epicarideans changes very little the overall patterns of
distribution, as demonstrated by the two figures provided (Figure 109). After
making these exclusions there remain about 166 species (218 with the epi-
carideans) that can be broken down into the following components (figures
in brackets include epicarideans):
1. True Caribbean/Bahamian species— 124 species, 74.8% [147, 67.5%].
These are the species recorded only from the Caribbean and the Bahamas.
The term endemic is avoided, as too little is known of the actual distribution
of many species. Of these species, 86 [87] have been recorded from a single
locality.
2. Species occurring south of the discussion area, and extending into
Brazil—5 species, 3.0% [9, 4.1%]. These low numbers indicate that the

great area of mixed-salinity waters resulting from the outflow of the Orinoco,
Amazon, Tocantins, and Parnaiba rivers form an effective barrier to the
movement of shallow-water isopod species.
3. Species having an amphi-Panamic distribution—7 species, 4.2% [8,
3.7% | (Table 5). In spite of the history of immergence and emergence of the
Isthmus of Panama, this very small amphi-Panamic component in the Carib-
bean isopod fauna suggests that most of this fauna has evolved since the last
emergence of the late Pliocene. Given the limited mobility of most isopod
species, the Panama Canal seems to have played a minimal role in contribut-
ing to this component.
4. Species occurring outside of the western Atlantic (but excluding the
amphi-Panamic species)—3 species, 1.8% [7, 3.2%].
5. The role of the Gulf of Mexico isopod fauna (see Clark and Robertson,
1982) in the composition of the Caribbean/Bahamian is complex and diffi-
cult to analyze. One hundred and thirteen species of shallow-water isopods
have been recorded from the Gulf of Mexico (Table 6). This number would
indicate that many species remain to be recorded in this region. Of these 113
species, 61 (54%) have also been reported from the Caribbean region. It is
therefore possible that there exists a true Gulf of Mexico fauna, whose evolu-
tion was perhaps spurred by the relative isolation and reduction of the Gulf

of Cape Kennedy, which would indicate a significant cooler-water compo-
nent. What proportion of originally Gulf species have spread into the Carib-
bean, and what proportion of Caribbean and temperate east coast species
have entered the Gulf, cannot yet be assessed, given our incomplete knowl-
edge of the Gulf fauna. Because of this unresolved situation, three categories
of species have been separated: species ranging from north of Cape Kennedy
into the Caribbean—6, 3.6% [12, 5.5%]; species occurring in the Gulf of
Mexico and the Caribbean—9, 5.4% [14, 6.4%]; species occurring north of
Cape Kennedy, in the Gulf, and in the Caribbean— 12, 7.2% [21, 9.6%] The
conclusion that the fauna of the Gulf of Mexico contains an endemic compo-
nent, a Caribbean component, and a warm-temperate component was also
reached by Topp and Hoff (1972), in an analysis of the pleuronectiform
fishes of the Gulf.
THE BAHAMAS
The Florida Current flowing through the Straits of Florida has been sug-
gested as a factor in reducing the movement of shallow-water fauna between
peninsular Florida and the Florida Keys on the west and the Bahamas on the
east (Briggs, 1974). Comparison of the number of isopod species on either
side of the Straits of Florida (13 from the Bahamas, 50 from southern penin-
sular Florida and the Florida Keys) supports this view. Of the 13 species
from the Bahamas, only four are “endemic,” three of these being interstitial
microcerberideans.

BERMUDA
Twenty-nine species of isopods have been recorded from Bermuda (Table 7).
Of these, nine are endemics (three being cave forms). The remaining 20
species have all been recorded from the Caribbean region, indicating a strong
subtropical connection, in spite of the relatively high latitude (32°15'N). Al-
though Bermuda is of Eocene or Oligocene age, the tropical fauna was prob-
ably decimated by the low temperatures of the last Pleistocene glaciation
(Briggs, 1974:76).
CAVE ISOPODS
With the expanding efforts of cave divers, more and more true stygobiont
forms are being found. Concurrently, discussion of the origin of cave fauna
has spurred several theories, all invoking the geological history of the Carib-
bean area.
Among the isopods, cave forms have been found in four suborders, the
Asellota, Anthuridea, Flabellifera, and Microcerberidea. Two valuable dis-
cussions on the origin of cave crustaceans may be found in Stock (1986) and
Wagele (1985).
The only true cave asellote, Atlantasellus cavernicolus Sket, was collected
from Bermuda.

The anthuridean cave representatives are found in two families: the genus
Curassanthura Kensley in the Paranthuridae, and the genus Cyathura subgenus
Stygocyathura Botosaneanu and Stock in the Anthuridae (see Figure 110).
Three species of Curassanthura are known, one each from Curagao, Ber-
muda, and Lanzarote in the Canary Islands. Curassanthura halma Kensley,
from Curacao, is an interstitial form found in hypersaline waters. Curas-
santhura bermudensis Wagele was found in water of about 26%o salinity. The
Lanzarote species, C. canariensis Wagele, came from seawater in a lava cave.
Wagele (1985) suggests that this amphi-Atlantic distribution of Curassanthura—
is the result of plate tectonics separating an ancestral hypogean progenitor
that had a Tethyan distribution.
The genus Cyathura has representatives in the sea, in estuarine-brackish
habitats, and in freshwater caves, and is found in the Atlantic, Indian, and
Pacific oceans. This widespread distribution suggests a very long history for
the genus. Using the morphology of the male copulatory stylet, Wagele
(1985) suggests that marine ancestors, having a Tethyan distribution, en-
tered freshwater interstitial habitats. The series of regressions of sea level
during the Pleistocene probably served further to isolate these freshwater
forms.

ZOOGEOGRAPHY DAs
The flabelliferan family Cirolanidae contains five stygobiont genera in the
Caribbean: Anopsilana, Arubolana, Bahalana, Creaseriella, and Haptolana (Figure
111). Six other genera are known from the North American continent:
Antrolana, Cirolanides, Mexilana, Speocirolana, Sphaerolana, and Troglocirolana, all
of which, except Antrolana from the Appalachian Valley of Virginia, occur in
Mexico and Texas (see Notenboom, 1981). A few of these forms occur in
brackish water, but most are found in freshwater of caves. Cave cirolanids
are also known from Palau, North and East Africa, Madagascar, Bulgaria,
Greece, Jugoslavia, Israel, France, and Spain. This widespread distribution
again suggests a Tethyan marine origin, with dispersal and isolation due to
sea regressions.
The suborder Microcerberidea and the asellotan family Microparasellidae
contain almost entirely interstitial forms, although few occur in caves. At
least two genera, Microcerberus and Angliera, have very widespread distribu-
tions and are known from marine, brackish-water, and freshwater habitats,
and may well have a history similar to that of Cyathura.

records for the Caribbean and associated areas, or instituting a major
new taxon. It was thought useful to include these, if only in an appendix,
to make the work as current as possible. The relevant taxa are listed
alphabetically, with the full citation given below.
